I’ve used Toruqe3D and then went to Unity…but UE4 just blows my mind with how RIDICULOUSLY AWESOME IT IS. Seriously Epic fully deserve their name in my mind. Honestly I don’t make games to make money, I mean sure, it is a business but this is the mentality that drove our current industry into the flood of DLC’s that it is today. It’s up to us to take a stand against it, kudos to CD Project RED for standing firm with this policy. Fun before cash. Yes devs need to eat, but currently the industry is ripping off gamers EA and Ubisoft being the prime examples.
Epic has gained a lot of respect from me by making UT4 a free game, and their engine just reinforced that.
Anyway I was just worried that I’d end up being bogged down accounting rather than making games, but I guess I’ll find out after I make one 
As for Unity vs UE4…I think the winner is clear.
One last question though, it’s very off-topic but hey, might as well ask: I only know C#, I’m in the process of learning Blueprints which seems like a visual representation of C#. How hard would the transition between BP to C++ with C# background would be?
